TIRE.

Specification of Letters Iatent. Pafnted Mar; 24, 191 4.

Application led January 11, 1913. Serial No. 741,563.

To all wiz-omit may concern Be it known that I, LYMAN H. FERGUSON, a citizen of the 'United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Tires, of which the fol-l looseness between the body and the partition causes considerable friction .and when the machineis driven at high speed this friction causes extreme heat ywhich blisters the tire thus permitting the ingress o'f the gravel and water and the deterioration of the tire.

Itis the object of this invention to overcome these diliiculties and broadly speaking consists in providing a frictionless partition adapted to absorb the shocks received by the tire.

A further object of the invention is to provide a tire having a plurality of partitions so constructed and connected througlr out to the walls of the tire so that there will be no friction between the walls and the partition and so that the walls of the tire or body may be spread conveniently to remove the core.

Still'another object of the invention is the provision of a tire of this character having a plurality of partitions bridged across the interior of the same and each provided with va vertical slot whose diameter increases as the slot extends inwardly so that compression on the tire will not bring the walls of the slot together whereby friction would 4 be produced, and thus avoiding this objection.`

Further objects of this invention will appear as the following specific description is read in connection with the accompanying drawing which forms a part of this application, and in which Figure 1 is a fragmentary elevation partly in section. Fig. 2 is a transverse sectional View through one of the partitions of the between two of the partitions and showing the .walls of the tire partly spread and thusm d1cating how the core may bev removed. F 1g. L is a fragmentary sectional perspec tive view.` Fig. 5 is a section. on the line l5-5 of Fig; 1.

vvReferring more particularly to the draw- 1ng, 1 represents .an ordinary wheel felly provided with any suitable type of clencher rim adapted tovreceive and secure the lateral flanges 3 of the tire body 4 to the felly. 'Thls tire body comprises an annular circumferentially split hollow member having a plurality of partitions 5 extending transversely across the interior of the body and connected to the body through out their entire circumference. Each partition is constructed similarly and may be formed of a somewhat softer or more elastic rubber than that of which the body 4 is formed or they may be constructed of the same quality and type of rubber and the body may -be reinforced with inter-embedded layers of a suitable reinforcing fabric. Each partition is split or slotted as shown at 6, the walls of the slot meeting for a distance from the bottom of the tire which is equal or greater than the thickness or depth of the clencher rim. The slots are then widened as shown at 7 so as to have their walls considerably separated and this widened slot merges into an enlarged opening 8 formed approximately in the center of the partition. Immediately above the opening S are openings or apertures 9, the lower wall of which is provided with an upward extension or knob l0 which is adapted to engage the upper wall of the opening when the tire is forcibly collapsed so as to assist in carrying the tire back to normal position.

By connect-ing the partition throughout its circumference to the walls of the tire Fig. 3 is a detail sectional viewltalen4 body there is no relative movement between the partition and the tire body and consequently no friction betweenv these parts to hea-t up the tire. It will be noticed that upon pressure being applied the walls of the slot 6, or more correctly speaking, the walls I ofthe enlarged or widened portion of the slot 6 will be spread apart instead of bei-ng brought together and the walls of said slot where they meet being below the pointof bend of;` the partition and body of the tire and areizfrced together in a direct transverse A.line across the tire so that there is no lsliding-I novement between the Walls of the slot and p consequently no frictionl is produced in these parts.

What'is claimed is A tire comprising an annular hollow body circumferentially split and split partitions extending acr'oss the interior to the body and formedintegral with the tire throughout their circumferences, said partitions having an enlarged central opening communicating with the split, the Walls of said split contacting for a predetermined distance above the base of the p artitions and being separated frolnthe contacting portions to thc 15 .central opening, said partition having openings arranged radially above the central opening2 the inner Walls of the latter openings being formed to produce outwardly extending lugs adapted to contact with the 20 opie of this patent may be obtained for five cents each. by addressing the Commissioner of Patente Washington.
